Design – Xiaomi 20000mAh Power Bank Review

Xiaomi 20000mAh Power Bank Review

Xiaomi power banks are mostly out of stock. That is because they sell as soon as they are in stock. One of the primary reasons for that was because those were encased in a premium metal casing and felt nice and looked even nicer, not to mention their affordability. Well it seems Xiaomi is moving on now with their new 20000 mAh beast as for this power bank instead of aluminum, the Chinese company has gone with lightweight plastic instead. The externals of the 20000mAh power bank sport embossed dots to aid with grip when you’re handling it. Maybe they felt the aluminum casing made the power bank slippery..or maybe not. The aesthetics of the device are still great and Xiaomi did not fail to mention that this power bank is very light at 338g for its massive capacity, adding that it is much lighter than 2x 10000 mAh Mi power banks.

Charging – Xiaomi 20000mAh Power Bank Review

With 20000mAh of juice, this particular power bank can charge several phones with enough left over for other devices. The Mi Power Bank is capable of fast charging devices (output of 2A) and Xiaomi has added fast charging input to it too so that you do not have to wait too long for it to charge.


For us, it took almost 8 hours for the device to fully charge. It sounds like a lot but you can just plug it in before sleeping and plug it out and take it with you the next day.

The Science – Xiaomi 20000mAh Power Bank Review

Obviously, the 20000mAh capacity isn’t the “real-life capacity” of this power bank. Many factors which like heat, physics and energy transfer all contribute to the reduced, real rating of power banks.


We ran some tests and managed to record a real rating of 17786mAh when the power bank was charged and were able to extract around 14108mAh worth of juice from it.

Verdict – Xiaomi 20000mAh Power Bank Review

Xiaomi 20000mAh Power Bank is the best power bank for constant travellers and for people going on long trips, be it business or leisure. The long charge time is let down, but for a power bank this size, not new technology has a better answer.


This power bank is a winner when it comes to shooing your battery woes on rough office days or on long trips. Definitely worth a buy.
